What's the best sports related fight you've ever seen?

Some friends and I visited San Antonio to see a Van Halen concert on Saturday. While we were there the NBA finals were going on. We decided to go down to a sports bar on the River Walk and watch the game. We were in a crowded group of people all trying to watch the game and almost everyone was rooting for OKC. When the Miami Heat made their entrance a man in the middle of the crowd cheered, " Go Lebron!" Two men standing in front of him then turned around and knocked him the fuck out. I swear I thought I heard "fatality!" screamed in the background. So tell me, What's the greatest sports related fight you have ever seen?
